Due to the high temperature of the rubber sole, the user needs to clamp it with a clamping tool. However, the rubber sole with high temperature and the rubber sole that has not been completely cooled down are soft as a whole, and the rubber sole is not completely molded. The clamping part of the rubber sole that has not been molded is easily deformed, resulting in a reduced yield rate of rubber sole production.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 3As shown, the utility model provides a rubber sole hot pressing molding device, including a bottom plate 1, the top of the bottom plate 1 is fixedly connected to a workbench 2 through a bracket, the top of the workbench 2 is fixedly connected to a lower heating mold 3, the top of the lower heating mold 3 is provided with an upper heating mold 4, the top of the upper heating mold 4 is fixedly connected to a rotary plate 5, the right side of the rotary plate 5 is rotatably connected to the surface of the workbench 2 through a hinge, the left side of the top of the rotary plate 5 is rotatably connected to an electric cylinder 6 through a hinge, the top of the electric cylinder 6 is rotatably connected to the surface of the workbench 2 through a hinge, and a lossless ejection mechanism 7 is provided inside the lower heating mold 3.

[0021] refer to Figure 3 The lossless ejection mechanism 7 includes a top plate 71, which is located inside the lower heating mold 3. A lifting rod 72 is fixedly connected to the bottom of the top plate 71, and the bottom of the lifting rod 72 passes through the bottom of the workbench 2. An inclined block 73 is provided at the bottom of the lifting rod 72. An electric push rod 74 is fixedly connected to the right side of the inclined block 73. A mounting plate frame 75 is fixedly connected to the bottom of the electric push rod 74. The top of the mounting plate frame 75 is fixedly connected to the bottom of the workbench 2. A lower spring assembly 76 is fixedly connected to the surface of the lifting rod 72, and the top of the lower spring assembly 76 contacts the bottom of the workbench 2.

[0022] As a technical optimization solution of the utility model, by providing a lossless ejection mechanism 7, the formed but unmolded high-temperature rubber sole can be ejected losslessly, thereby avoiding damage to the rubber sole during removal and improving the yield rate of rubber sole production.

[0023] refer to Figure 3 The bottom of the lifting rod 72 is rotatably connected to a pulley 8 via a pin, and the surface of the pulley 8 contacts the surface of the inclined block 73.

[0024] As a technical optimization solution of the utility model, by setting the pulley 8, the lifting rod 72 can be isolated from the contact with the inclined block 73, avoiding the inclined block 73 from rubbing against the surface of the lifting rod 72 when moving, causing the surface of the inclined block 73 to be worn, thereby improving the installation safety of the inclined block 73.

[0025] refer to Figure 3 The front and rear sides of the inclined block 73 are slidably connected with a slide rail 9 , and the surface of the slide rail 9 is fixedly connected to the inner wall of the mounting plate frame 75 .

[0026] As a technical optimization solution of the utility model, by setting the slide rail 9, the inclined block 73 can be slid stably to avoid shaking during the sliding movement of the inclined block 73, which may cause the inclined block 73 to loosen, thereby improving the sliding stability of the inclined block 73.

[0027] refer to Figure 2 Support blocks 10 are provided on both sides of the bottom of the top plate 71 , and the bottom of the support block 10 is fixedly connected to the inner wall of the lower heating mold 3 .

[0028] As a technical optimization solution of the utility model, by setting the support block 10, the top plate 71 can be limited to avoid excessive movement of the top plate 71, which causes the top plate 71 to be uneven with the lower heating mold 3, thereby improving the working stability of the top plate 71.

[0029] refer to Figure 1 A reinforcing rib 11 is fixedly connected to the right side of the top of the workbench 2. The number of the reinforcing ribs 11 is several, and the several reinforcing ribs 11 are distributed at equal distances.

[0030] As a technical optimization solution of the utility model, by providing reinforcing ribs 11, the structural strength of the workbench 2 can be strengthened to prevent the workbench 2 from deforming during long-term use, which would cause the workbench 2 to be unable to be used normally, thereby improving the use stability of the workbench 2.

[0031] refer to Figure 2 A weight-reducing groove 12 is provided on the left side of the workbench 2. The number of the weight-reducing grooves 12 is several, and the several weight-reducing grooves 12 are distributed at equal distances.

[0032] As a technical optimization solution of the present invention, by providing the weight-reducing groove 12 , the weight of the workbench 2 can be reduced, thereby preventing the workbench 2 from being difficult to move during use and reducing the difficulty of moving the workbench 2 .

[0033] The working principle and use process of the utility model are as follows: when in use, after the lower heating mold 3 and the upper heating mold 4 have finished processing the rubber sole and the rubber sole needs to be taken out, the upper heating mold 4 and the lower heating mold 3 are separated by the electric cylinder 6, and the electric push rod 74 is started. The electric push rod 74 drives the inclined block 73 to move to the left, and the lifting rod 72 of the inclined block 73 moves upward. The lifting rod 72 drives the top plate 71 to move upward. Since the contact area between the top plate 71 and the rubber sole is large, the rubber sole is lifted up and subjected to uniform force, and the bottom of the rubber sole will not be damaged by the driving force, thereby having the advantage of improving the yield rate.

[0034] To sum up: the rubber sole hot pressing molding device, through the coordinated use of the bottom plate 1, the workbench 2, the lower heating mold 3, the upper heating mold 4, the rotary plate 5, the electric cylinder 6 and the lossless ejection mechanism 7, solves the problem that when the lower hot pressing mold is finished working, it is necessary to take out the rubber sole formed inside. Due to the high temperature of the rubber sole, the user needs to clamp it with a clamping tool. However, the rubber sole with high temperature and the rubber sole that has not been completely cooled down are soft as a whole, the rubber sole is not completely molded, and the clamping part of the rubber sole that has not been completely molded is easily deformed, resulting in a reduced production yield of the rubber sole.
